1. these results demonstrate a novel role of the p6 domain in the specificity of Pr55(Gag)-RNA interactions, and strongly suggest that the p6 domain contributes to the discrimination of HIV-1 gRNA from cellular and spliced viral mRNAs, which is necessary for its selective encapsidation. PMID:29954247
2. High-resolution structures of HIV-1 Gag cleavage mutants determine structural switch for virus maturation. PMID:30217893

9. Data report that p17 is released in an active form by Gag-expressing cells. The secretion of p17 takes place at the plasma membrane and involves the interaction of p17 with PI(4,5)P2. The release of p17 occurs following its cleavage from Pr55Gag by cellular aspartyl proteases. PMID:27905556

13. The authors found that the overexpression of YTHDF proteins in cells inhibited HIV-1 infection mainly by decreasing HIV-1 reverse transcription, while knockdown of YTHDF1-3 in cells had the opposite effects.

22. Taken together, these data demonstrate that cytotoxic-T-lymphocyte-driven escape mutations within p24 Gag restricted by protective HLA class I alleles have a significant impact on HIV-1 capsid stability that might contribute to the persistent control of viral replication observed despite viral escape from cytotoxic-T-lymphocyte responses. PMID:27279617
23. Altogether, these data revealed that targeting of HIV-1 Gag to the virus-containing compartments in macrophages requires the NC domain-dependent multimerization. PMID:27440886

25. Gag is able to block the assembly of type II noncanonical stress granules to facilitate continued Gag protein synthesis. PMID:27025252
26. The authors find that HIV-1 nucleocapsid mimics the PDZ domains of syntenin, a membrane-binding adaptor involved in cell-to-cell contact/communication, to capture the Bro1 domain of ALIX, which is an ESCRTs recruiting cellular adaptor. PMID:26962944
27. These data demonstrate that mutations in the CypA binding site of the capsid resulted in higher capsid stability and hampered infectivity in macrophages. PMID:26414211

30. HIV-1 nucleocapsid protein localizes efficiently to the nucleus and nucleolus. PMID:26967976
31. HIV-1 depends on host-cell-encoded factors to complete its life cycle; data suggest NAF1 (HIV Nef-associated factor 1) promotes nuclear export of un-spliced HIV-1 gag mRNA; association between NAF1 and CRM1 (exportin 1) is required for this function. PMID:26733199

33. Data suggest that minus-strand strong-stop DNA exhibits four binding sites for NC (nucleocapsid protein, 55-amino acid gene product of gag); NC-mediated annealing process does not rely on a single pathway (zipper intermediate or kissing complex). PMID:26668324
34. Dynamic interactions occur among HIV-1 RNAs, and stabilization of the RNA dimer requires Gag protein. PMID:26712001
35. The data suggest that once the SP1 Region of HIV-1 Gag becomes helical, its propensity to self-associate could contribute to Gag-Gag interactions and thus to particle assembly. PMID:26637452
36. These data support a model in which the major homology region residues act just after membrane targeting, with some residues promoting stability and another promoting multimerization of the membrane-targeted assembling Gag oligomer. PMID:26656702
